Fig. 2 OPLS-DA applied to spectral data (x-variables) and metal content and plant biomass data (y-variables). (a.) Scores plot displaying t[1] vs t[2], the observations are colored according to the tissues of the plants: leaves (green circle, LE), stems (blue square, ST). (b.) Scores plot t[1] vs t[2], the observations are colored according to the health status of the plants: vigorous (yellow circle, V), weak (red square, W). (c.) Loading plot displaying the relationship between the x-variables (spectral regions) and the y-variables (metal content and plant biomass) for the first and second predictive components pq[1] vs pq[2] (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.).
